Miniaturization is the watchword of progress. Nanoscience - building structures on the scale of a few atoms - has long been at the forefront of chemistry for some time now. Recently, researchers at The University of Tokyo developed the new strategy to construct the subnanosized metal aggregates, ...
LMU chemists have identified a mechanism that allows molecules to diffuse rapidly on the already crowded surface of a solid-state catalyst – an important capability, especially for efficient catalysis under industrial conditions. The use of efficient catalytic agents is what makes many technical ...
Chemists discover way to simplify synthesis of valuable precursor for drugs, other compounds
Rice University scientists have given organic chemists a boost with their latest discovery of a one-step method to add nitrogen to compounds for drugs, pesticides, fertilizers and other products. Rice synthetic organic chemist László Kürti said the method is a major step forward as it quickens ...
Directed evolution of a designer enzyme with an unnatural catalytic amino acid
The impressively high conversion rates of natural enzymes partly result from increasing the catalytic activity of a selected few amino acid side chains through precise positioning within the protein binding cavity. Scientists have now demonstrated that such fine-tuning is also possible for ...
Active photocatalyst: 2D/2D heterojunction of black phosphorus and bismuth tungstate
A significant advance in the photocatalytic activity of conventional materials is demonstrated by a two-dimensional heterostructure comprising nanolayers of two semiconductors: black phosphorus and bismuth tungstate. As researchers have reported in the journal Angewandte Chemie, this catalyst ...
Ammonia synthesis through electroreduction of nitrogen on black phosphorus nanosheets
More than 100 years after the introduction of the Haber–Bosch process, scientists continue to search for alternative ammonia production routes that are less energy demanding. Chinese scientists have now discovered that black phosphorus is an excellent catalyst for the electroreduction of nitrogen ...
A chemical reaction pathway central to plant biology have been adapted to form the backbone of a new process that converts water into hydrogen fuel using energy from the sun. In a recent study from the U.S. Department of Energy's (DOE) Argonne National Laboratory, scientists have combined two ...
How crystalline structure can affect the performance of MnO2 catalysts
Scientists at Tokyo Institute of Technology (Tokyo Tech) have developed and analyzed a novel catalyst for the oxidation of 5-hydroxymethyl furfural, which is crucial for generating new raw materials that replace the classic non-renewable ones used for making many plastics. It should be no ...
Chemical engineering researchers develop self-powered microfluidic sheet that wraps, flaps and creeps
The "magic carpet" featured in tales from "One Thousand and One Nights" to Disney's "Aladdin" captures the imagination not only because it can fly, but because it can also wave, flap, and alter its shape to serve its riders. With that inspiration, and the assistance of catalytic chemical ...
The vanished mirror image
Enantiomeric molecules resemble each other like right and left hands. Both variants normally arise in chemical reactions. But frequently only one of the two forms is effectual in biology and medicine. Hitherto, completely converting this mixture into the desired enantiomer was deemed impossible. ...
